What cron format is produced?

Can it do the reverse?
For cron → English, use the Cron Expression Parser tool; this tool goes from English → cron.
Do I need my own API key?
Yes. This tool is bring-your-own-key: paste your own Anthropic or OpenAI key and it is used only for that single request — never stored on our servers.
